SD-08 Manufacturer's Instructions

Submit Manufacturer's instructions for Panelboards including special provisions required to install equipment components and system packages. Special notices shall detail impedances, hazards and safety precautions.

PART 2 PRODUCTS

2.1 PANELBOARDS

Panelboards shall be NEMA 12, main circuit breaker type, totally enclosed power-distribution panelboards in a steel cabinet, dead-front circuit breaker type with copper buses, and surface-mounted. Panelboards shall not be larger then 20" wide by 8" deep to fit on limited wall space. Ensure panelboards conform to NEMA PB 1 and NEMA AB 1. Branch circuit panels shall have buses fabricated for bolt-on type circuit breakers.

Provide distribution panelboards with isolated full-capacity bus providing spaces for single-pole circuit breakers/switches and spaces indicated.

Provide panelboards with a separate copper grounding bus bonded to the enclosure. Grounding bus shall be a solid copper bus bar of rectangular cross section equipped with binding screws for the connection of equipment grounding conductors.

Each panelboard, as a complete unit, shall have a short-circuit current rating equal to or greater than the integrated equipment rating shown on the panelboard schedule or as indicated.

Bus bars shall be copper. Bus bar connections to the branch circuit breakers shall be the "distributed phase" or "phase sequence" type.

Single-phase, three-wire panelboard busing shall be such that when any two adjacent single-pole breakers are connected to opposite phases, two-pole breakers can be installed in any location. Three-phase busing shall be such that when any three adjacent single-pole breakers are individually connected to each of the three different phases, two- or three-pole breakers can be installed at any location. Current-carrying parts of the bus assembly shall be plated. Mains ratings shall be as shown.

Mechanical lugs furnished with panelboards shall be cast copper or copper alloys of sizes suitable for the conductors indicated to be connected thereto.

2.2 CIRCUIT BREAKERS

Circuit breakers shall be the molded-case type. Trip ratings shall be as indicated.

Interrupting rating of circuit breakers shall be as indicated. If not shown, the interrupting rating for circuit breakers in 120/240-volt panelboards shall be not less than 10,000 amperes rms symmetrical, and that for breakers in 480-volt panelboards shall be not less than 14,000 amperes rms symmetrical.

SECTION 26 24 16.00 40 Page 3

Circuit breakers shall be bolt-on type. Plug-in type is not acceptable.

In branch circuit panelboards, branch circuit breakers feeding convenience outlets shall have sensitive instantaneous trip settings of not more than 10 times the trip rating of the breaker to prevent repeated arcing shorts resulting from frayed appliance cords. Single-pole 15- and 20-ampere circuit breakers shall be UL listed as "Switching Breakers" at 120 volts

ac. Provide UL Class A (5-milliampere sensitivity) ground fault circuit protection on 120-volt ac branch circuit as indicated. This protection is an integral part of the branch circuit breaker that also provides overload and short-circuit protection for branch circuit wiring. Tripping of a branch circuit breaker containing ground fault circuit interruption is not to disturb the feeder circuit to the panelboard. A single-pole circuit breaker with integral ground fault circuit interruption requires no more panelboard branch circuit space than a conventional slide pole circuit breaker.

Circuit breakers shall be lockable in the off-position for lock-out tag-out purposes.

Ensure connections to the bus are bolt-on type.

When multiple wires per phase are specified, furnish the circuit breakers with connectors made to accommodate multiple wires.

Ensure circuit breaker spaces called out on the drawings are complete with mounting hardware to permit ready installation of the circuit breakers.

2.3 DIRECTORY CARD AND HOLDER

Mount a directory card on the inside of hinged fronts and doors 0.030-inch thick minimum plastic in a metal frame, with spaces for circuit numbers, outlets controlled, and room numbers. Directory card shall identify each branch circuit with its respective and numbered circuit breaker.

2.4 FACTORY TESTING

Test complete panelboards in accordance with UL 67.

2.5 PRECAUTIONARY LABEL

To ensure persons are aware of immediate or potential hazard in the application, installation, use, or maintenance of panelboards, each panelboard shall be conspicuously marked on the trim or dead front shield with the text (or equivalent) DANGER symbol. If the panel is supplied with a door, ensure the label is visible when the door is in the open position.

2.6 PR2 TVSS

The new TVSS for panelboard PR2 (120/240 V, single phase) shall be Control Concepts, Model IM120S160 or approved equal in accordance with the salient characteristics listed below, and must be interchangeable with the existing TVSS for panelboard PR1. The new TVSS for PR2 shall connect to PR2 through the existing security panel, similar to the existing TVSS. The salient characteristics are as follows:

Voltage: 120/240 V, single phase, 3W + G, 50-60 Hz

SECTION 26 24 16.00 40 Page 4

TVSS: 330 V pk, (L-N, L-G, N-G), 600 V pk (L-L) UL approved

PART 3 EXECUTION

3.1 INSTALLATION

Install panelboards as indicated and in accordance with the manufacturer's instructions. Fully align and mount panels so that the height of the top operating handle does not exceed 72-inches above the finished floor. Panels shall be plumb and square.

Directory-card information shall be typewritten in capital letters to indicate outlets controlled and final room numbers served by each circuit and shall be mounted in holders behind protective covering.

3.2 SITE TESTING

Panelboards shall be given continuity and insulation tests after the installation has been completed and before the panelboard is energized.

Provide test equipment, labor, and personnel as required to perform the tests as specified. Conduct Continuity tests using a dc device.

Conduct insulation tests on 480-volt panelboards using a 1,000-volt insulation-resistance test set. Record readings every minute until three equal and consecutive readings have been obtained. Resistance between phase conductors and between phase conductors and ground shall be not less than 50 megohms.

Conduct insulation tests on panelboards rated 300 volts or less using a 500-volt minimum insulation-resistance test set. Record readings after 1 minute and until the reading is constant for 15 seconds. Resistance between phase conductors and between phase conductors and ground shall be not less than 25 megohms.

Record test data and include the location and identification of panelboards and megohm readings versus time.
